| Title | High Brightness LED Driver |
| Description | The AT9919 is a PWM controller IC designed to drive high brightness LEDs using a buck topology. It operates from an input voltage of 4.5 to 40VDC and employs hysteretic control with a high-side current sense resistor to set the constant output current. The operating frequency range can be set by sel. |
| Features |
